The dielectric properties of some liquid crystalline cyanobiphenyls were investigated using dielectric spectroscopy methods in a wide frequency range from 10-4Hz to 105Hz. There are several significant parameters that can be obtained using this method, such as dielectric permittivity and electrical conductivity. Additionally, nature of the tested material at a given frequency range and for a given electric field range (to 7(DOT)104V/m) was investigated. This nature seems to be rather resistive. However, a capacitive nature becomes significantly responsible for the material behavior in low frequency range--below 1 Hz.
